I have a global variable going out of scope and I'm not sure why. Below is a subset of my code. I have confirmed that all assert statements are true both by appropriate debug prints and using a debugger walk through. My global var just disappears.

For those wondering why I don't just pass it, its because in the real program there are functions under Bar that don't need/use gVar except for error/debug printing so I thought this was a cleaner way to pass rather than pass it constantly, often to functions it isn't used in. 

my $gVar;

sub Foo
{

   my $listOfHashRef = generateList();
   my $functionPtr;

   foreach $gVar (@$listOfHashRef) {
       $functionPtr = $gVar->{funPtr};
       # Assert:  $gVar has all of its values here
       $functionPtr->();
   }
}

# Assert:  The $gVar->{funPtr} does indeed point to Bar
sub Bar
{
    print "$gVar\n";
    # Assert:  $gVar is null
}
